Facebook is to unveil a new look for its popular newsfeed next week, the
latest move to revamp key elements of the one billion-member social
networking giant.

Facebookwill showcase the newsfeed makeover at a media event on March 7 at its Menlo Park, California headquarters, the company said in an emailed invitation to the press on Friday.

The event will be Facebook's second high-profile product event this year, following the rollout of its social search feature in January.

Facebook's newsfeed, which displays an ever-changing stream of the photos, videos and comments uploaded from a user's network of friends, is one of the three "pillars" of the service, along with search and user profiles, CEO Mark Zuckerberghas said.

The last major update to Facebook's newsfeed was in September 2011. Since then, the company has incorporated ads directly into the feed and the company has shifted its focus to creating "mobile first experiences," as more people now access the social network every day on mobile devices than on desktop PCs.

The mobile version of Facebook still lacks many of the features available on the PC version, said Brian Blau, an analyst with industry research firm Gartner. "So maybe this is a way to bring some of that together," he said.
